I fully understand how you feel... I know about the bird in the hand thing. But even If I lose it all and I have done that several times, I only need to hit one of these damn things and wa la, the patient makes a full and successful recovery.
I bought this one a .0045, If I get out now, I have made a nice piece of change. But I could also try to get this plane to flyer higher at the risk of crashing it into the ocean. Either way, it's going to be a hell of a ride.
